FERGUSON AND BEZIER CURVES Palash Luthra Sachin Maheshwari Netaji Subhas Institute of Technology New Delhi-110078 India 1. CURVES-DEFINITION 2. NEED OF CURVES March 2013 A line or outline that gradually deviates from being straight for some or all of its length. Curves play a very significant role in CAD modeling‚ especially‚ for generating a wireframe model‚ which is the simplest form for representing a model. We can display an object on a monitor screen in three different computer-model forms:

However‚ the construction of such an adaptive model needs the knowledge

to solve in order to find the cubic spline passing through the three points (0‚ 1)‚ (0.5‚ 2) and (1‚ 4). Plot the resulting spline (you may use the file plotspline.m). 5. What happens to the condition number of the matrix S used in cubic spline interpolation as the size n becomes large (you may use the file splinemat.m)? 6. A parabolic runout spline is the interpolating function you get by changing the condition f ′′ (x1 ) = f ′′ (xn ) = 0 to the condition that p1 (x) and pn−1 (x) should be quadratic

Determining g on an Incline During the early part of the seventeenth century‚ Galileo experimentally examined the concept of acceleration. One of his goals was to learn more about freely falling objects. Unfortunately‚ his timing devices were not precise enough to allow him to study free fall directly. Therefore‚ he decided to limit the acceleration by using fluids‚ inclined planes‚ and pendulums. In this lab exercise‚ you will see how the acceleration of a rolling ball or cart depends on the ramp

a study conducted by Deng and Ma on the issue of interpolation of loop subdivision surfaces. Deng and Ma argued that the most efficient way to create a detailed graphic is utilizing the mathematics behind the concept of interpolation of loop subdivision‚ to create this extreme detailed graphic. Deng and Ma used complex graphics such horse‚ a knot and an ant to compare the difference using different concepts‚ it was obviously using the interpolation of loop subdivision was more clear and detailed.
